You already film your training. CaliTimer gets the real hold time out of that footage, keeps every set in a training log, and exports a clip with the measured time burned in. TIME IT โ€ข Record a set in the app, or bring in a clip you filmed earlier with Time a Clip. โ€ข Review it on a marked timeline: drag the handles to the exact frame a hold starts and breaks, add a hold, or delete one that isn't real. โ€ข On handstand, front lever and tuck front lever, CaliTimer fills the hold time in for you. On everything else you mark it, a couple of seconds either way. Imported clips are always marked by hand. LOG IT โ€ข 78 exercises in ten families: front lever, back lever, planche and handstand variations, plus core, legs, push, pull and grip work. Timed holds and counted reps in one place. Can't find yours? Create it. โ€ข Build a session from several exercises. Log each set as hold time or reps, with added weight, resistance bands (use several at once) and RPE. Add a note to any exercise. โ€ข A rest timer counts down between sets. โ€ข Every session is a card in your log that opens into full detail, with your personal bests starred. Your week, time trained, sets and sessions is on the Train screen. โ€ข Kilograms or pounds, your choice. SHARE IT โ€ข Clip It exports a set as a clip trimmed to the hold, with the real measured time burned into the footage. Choose the typeface, colour, size, background and position, then save it or share it. โ€ข Filmed a hold months ago? Bring it in with Time a Clip, mark the hold on the timeline, and log it if it belongs in your record. PRIVACY โ€ข Your training data never leaves your phone. โ€ข Pose analysis, used for auto-detect, runs on-device with Apple's Vision framework, which returns joint positions โ€” not images. โ€ข No account. No sign-up. No analytics. No ads. No third-party SDKs. โ€ข Recordings stay on your device and are deleted when a session ends unless you save them to your camera roll.

About

Height Predictor AI

Features
Read full description

See where your height is headed โ€” and make every growth year count. HOW IT WORKS 1) Take the 2-minute quiz โ€” age, height, parents' heights, sleep, food. 2) Get your predicted adult height range โ€” the Khamis-Roche method, shown honestly as a range. 3) Start the daily plan for the rest โ€” posture, sleep and nutrition habits, one checklist a day. TallPath predicts your adult height range from the factors that actually matter: your current height, your age, your parents' heights, and how you sleep, eat, and move. The prediction uses the Khamis-Roche method, a peer-reviewed pediatric formula โ€” shown honestly as a range, because genetics set the range and habits decide where you land. YOUR PREDICTION โ€” Current height vs. predicted adult range, updated monthly as you log progress. YOUR DAILY PLAN โ€” A personalized checklist of posture, sleep, and nutrition habits built from your quiz answers. Streaks, a calendar view, and tasks you can complete any time before midnight. TRAIN โ€” A growing library of posture and mobility exercises with guided timers, browsable and repeatable from day one. AI COACH โ€” Ask anything about posture, sleep, nutrition, or your prediction. Your coach knows your plan and answers 24/7. PROGRESS โ€” Log your height, watch the chart move, and get a monthly report comparing prediction to reality. TallPath Premium is available as a weekly or yearly subscription or a one-time lifetime purchase. Subscriptions renew automatically until cancelled at least 24 hours before the end of the period; manage or cancel anytime in your App Store account settings. Restore previous purchases from the paywall. TallPath is not a medical device and does not provide medical advice. Predictions are statistical estimates, not guarantees.
